I think going out to watch a movie all alone in the Cinema would feel to me like taking a ride on the bus.
There are people everywhere, but nobody wants to talk to anyone they don't know or recognize.
Thus you have no one to share your thoughts and opinions with; and if you do share, you might be interrupting them or breaching into their personal space.
I have been to New York several times, but I always feel kind of lonely out there even when there are people everywhere around me. Manhattan included.
The only bond I remember achieving was in the subway train where two people came and tried to trick me, and then someone gave me a hint not to fall for the trap. Not that I was going to, but it created the intimacy and something in common to talk about.
...I have never gone alone into the official Cinema building.
